Assuming you have a main form for your app, put a handler in the query
unload event of the main form:

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

The UnloadMode value will tell you why the form is being unloaded:

vbFormControlMenu
    The user chose the Close command from the Control menu on the form.
vbFormCode
    The Unload statement is invoked from code.
vbAppWindows
    The current Microsoft Windows operating environment session is
ending.
vbAppTaskManager
    The Microsoft Windows Task Manager is closing the application.
vbFormMDIForm
    An MDI child form is closing because the MDI form is closing.
vbFormOwner
    A form is closing because its owner is closing.

You can do a select case on UnloadMode if you need different responses.
You can then pop up a message to the user, and set Cancel = True if you
(or they) want to cancel the unload operation.

In some cases, i.e. the session is ending, Windows may close the
application anyway, but at least you can warn the user this way.
